Application filed September 14, 1908. Serial No.452j833. 1

To all whom it may concern:

Be it known that I, EDWIN F. MoRToN, a; citizen of the United States of America, and a; resident of Portland, county of Cumberland, State of Maine, have invented certain town or city. it is inconvenient to find the right place in the book each time the telephone is used or a number looked up.

The object of my invention is to provide an indexing attachment which maybe easily and quickly applied to 'such telephone directories by which the section of the book devoted to the particular town or city may be quickly found and the desiredname located, the whole device being preferably made with covers embracing the directory and attachments and forming a temporary binding of ornamental appearance. These objects are carried out by means of my present invention hereinafter shown and claimed.

I illustrate my invention by means of the accompanying drawing in which- Figure 1 is a; perspective view' of a telephone directory fitted up with my indexing and binding attachment,- Fig. 2 is a view of one of the indexing leaves and Fig. 3 is a section through the book.

In the drawing, 6, 6 represent the leaves of telephone directory which is bound with a paper cover.

In applying my attachment, I provide a series of leaves as D, each of which is preferably of about the same length as the ordinary leaves of the book with. an index letter d projecting from the front edge in the usual manner of index leaves. The width of the leaf D is preferably somewhat narrower than the leaves of the book so that it will lie between the book leaves without striking the rear of the book.

A perforated tab 01 is formed on each rear corner of the leaf D each of these tabs be-' ing located beyond the ends of the book leaves and preferably offset from the end of the index leaf itself. The tab as hereshown is also offset to the rear of the rear edge of- V the leaf D sothat when it is-in'serted between the leaves of thedirectory, the tabs will come approximately flush with the back of the bookiand beyond the end thereof.

Both the index letter projections-and-the tabs 0! are reinforced by cementing on a 'strip of cloth 01 other stron material. The front edge of the leaf immediately below the index letter is cut away to form a recess of to admit the finger more readily in turning over the leaves.

comprise the entire alphabet and I usually provide an extra leaf as D containing the name of the town or city to be indexed with =1; tab d at the top for this purpose. On the leaf D there areprinted lines for conveniently noting numbers commonly used and spaces for advertising. this feature being one of the most important ones in the device in point of usefulness because the leaves are very conspicuous in a telephone directory. The leaf D is composed preferably of very strong paper somewhat heavier than the ordinary leaves of the "book. I

The leaves D are inserted between the leaves of the directory in the space covered by the town or city to-be indexed the letters book. If any page of the book includes more than one letter, the several letters are placed 011 theanargin of the leaf D.

.In making up my book, I- preferably make use of a pair of covers a a the covers and the tabs being secured together by two bolts or rivets each of which passes through one of the rear corners of the cover and through the perforations of the, tabs binding all the parts together and forming a temporary tial and permanent I prefer to make use of two metal angle pieces I) one of which fits over the rear edge of each cover, each having an opening in the end through which the bolt passes. The two vertical flanges of the angle pieces thus'constitute the back of the book and the horizontal flanges serve to strengthen the whole structure. It will be understood that there is a flexible joint in fined by the angle piece.

The parts are fastened together as here shown by a tubular bolt j which extends through the tab perforations but is too small to pass through the holes in the cover being opposite the appropriate pages'in thebinder.- To make the binding more substanreinforcing Enough of the leaves D are furnished to y each corner at the point whereit is concated beyond the ends of the book leaves,

' whole together.

for telephone directories and other like provided with index letter tabs on the front edge thereofand adapted to be inserted between the leaves of the book, each index and the angle piece. A pair of round headed screws f engage screw threads in the ends of the tube and serve to hold the books consisting of a'series of index leaves provided with index letters on the front edge thereof and adapted to be inserted between the leaves of the book, each index leaf having a perforated tab at each rear corner located beyond the end of the book leaves and means for fastening said tabs together.

2. The herein described index attachment for telephone directories and other like books consistin of a series of index leaves leaf havinga tab at each rear corner 10- and ro ecting in rearvof the rear edge of said index leaf, and means for fastening said tabs together.

3.
